GIE Editor-in-Chief, Dr. Michael Wallace, highlights this article from the December issue “The emerging role of histologic disease activity assessment in ulcerative colitis” by Rish K. Pai, MD, PhD, et al. The decision about when to start and stop therapy for ulcerative colitis is increasingly made based on colonoscopy and histological assessment of activity ("treat …
Underwater ESD in saline solution using a bent-type knife for duodenal tumor
Post written by Mitsuru Nagata, MD, from the Department of Endoscopy, Shonan Fujisawa Tokushukai Hospital, Kanagawa, Japan. We present a case of a duodenal tumor that was treated by underwater ESD using a bent-type knife (Hook Knife J) and discuss potential advantages of underwater ESD. Most studies on underwater ESD involved the use of only …

Reusing an electrocautery-enhanced stent deployment catheter to place additional pigtail stents
Post written by Andrew C. Storm, MD, from the Mayo Clinic College of Medicine and Science, Rochester, Minnesota, USA. We have presented the novel reuse of the electrocautery-enhanced lumen-apposing metal stent deployment catheter to permit transduodenal wire access and stent placement to create a dual AXIOS cystgastrostomy and double pigtail cystduodenostomy. Management of disconnected pancreatic …

Endoscopic restoration of completely transected and prolapsed common bile duct
Post written by Jorge Vargas, MD, from the Social Security System of Costa Rica, Hospital of Liberia, Guanacaste, Costa Rica. During a regular ERCP, a forceful stone extraction of a big stone was performed, and a frightening complication occurred. The common bile duct prolapsed into the duodenal lumen. After several cannulation attempts, we were able …

New-generation full-spectrum endoscopy versus standard forward-viewing colonoscopy
Post written by Toyoki Kudo, MD, PhD, from the Digestive Disease Center, Showa University Northern Yokohama Hospital, Yokohama, Japan. Although colonoscopy is the gold standard for detection of colorectal adenomas, some adenomas are missed. Full-spectrum endoscopy (FUSE) allows for observation with a 330° angle of view, which is expected to decrease the miss rate. However, …

Pulley traction-assisted colonic ESD affords good visibility of submucosal layer
Post written by Satoki Shichijo, MD, from the Department of Gastrointestinal Oncology, Osaka International Cancer Institute, Osaka, Japan. We performed endoscopic submucosal dissection (ESD) for a laterally spreading tumor involving a diverticulum in the posterior wall of ascending colon. We performed traction-assisted colonic ESD using a clip-and-line, which usually makes ESD safe and efficient by …

Focal cryoballoon versus radiofrequency ablation of dysplastic Barrett’s esophagus
Post written by Sanne N. van Munster, MD, from the Department of Gastroenterology and Hepatology, St Antonius Hospital, Nieuwegein, and the Department of Gastroenterology and Hepatology, Academic Medical Center, Amsterdam, the Netherlands. This study is a comparison of endoscopic cryoballoon ablation and radiofrequency ablation for eradication of Barrett’s-related neoplasia. Radiofrequency ablation (RFA) is the standard …

In vivo diagnosis of intraductal papillary mucinous neoplasm with per-oral pancreatoscopy–guided confocal laser endomicroscopy
Post written by Yuki Tanisaka, MD, PhD, from the Department of Gastroenterology, Saitama Medical University International Medical Center, Saitama, Japan. Our patient was a 79-year-old man in whom computed tomography indicated expansion of the main pancreatic duct. Endoscopic ultrasound (EUS) showed expansion of the entire pancreatic duct but could not detect the villous protrusions. Endoscopic …
